Summary
Glanzmann's thrombasthenia is a rare autosomal recessive bleeding disorder caused by defects in platelet aggregation. In Glanzmann's thrombasthenia, platelets are deficient in the fibrinogen receptor GpIIb/IIIa necessary for proper platelet aggregation. This leads to easy bruising, mucosa bleeding, and prolonged bleeding from even minor cuts. It can also cause internal bleeding, which can be life-threatening.
